Ford, 64, said at the inaugural Rome Film Festival on Friday that he was delighted to team up again with directors Steven Spielberg and George Lucas for the film. Lucas co-wrote and executive produced the earlier films, which Spielberg directed.

"Indiana Jones 4" has been in development for over a decade, but the production has recently gained momentum. Lucas has said he and Spielberg, who would direct, are working on a script, though no details have been disclosed.
